Signs of potential violence in inmates may include all EXCEPT:

Excessive laughing is generally not considered a sign of potential violence in inmates. While humor and laughter can sometimes serve as a coping mechanism, they do not typically correlate with aggressive or violent tendencies. The other behaviors referenced—sudden aggressive behavior, isolation from peers, and unusual quietness—are more commonly understood as indicators of underlying distress or potential for violent outbreaks. Sudden aggression can manifest as a direct threat or risk to others, while isolation may reflect social withdrawal that can accompany feelings of hostility or frustration. Likewise, unusual quietness could indicate that an inmate is struggling emotionally and may be at a tipping point for acting out. Therefore, excessive laughing does not align with the recognized precursors of violent behavior in correctional environments.
